Identification Of Fungicide Thiram Using SERS

Introduction

Fungicides are used for high productivity in farming.

Retained fungicides in soil/water is harmful.

Existing detection methods are time consuming and sophisticated

In the current study, Thiram has been detected using SERS with 103 enhancement

Surface-enhanced Raman spectroscopy (SERS) – high sensitivity, short detection time and nondestructive detection.

Experimental Condition

• Raman Spectrometer:
• Model: IndiRAM P785_Tracer
• Laser excitation source
• Exposure time: 5 sec
• No of Acquisition: 5
• SERS: Liquid SERS

Results and discussion

• SERS shown enhanced Raman Signal
• Detected minimum of 0.1 µM of Thiram on varying Concentration
